Used in research as a fluorescent probe due to its strong emission properties from the naphthalene moiety, particularly in biological imaging. The compound's structure, featuring a biotin conjugate, allows it to bind selectively to specific proteins such as avidin and streptavidin, and enzymes, making it valuable in studying cellular processes. It is also employed in the development of biosensors, where its fluorescence response changes upon interaction with target molecules. Additionally, it has been explored in drug delivery systems for tracking the distribution of therapeutic agents within cells.
